Upgrade your Kenwood's radio to the digitally-enhanced sound of HD Radio™ — once you connect the KTC-HR300 hideaway tuner, participating FM stations approach CDs in sound quality, while AM stations sound as good as today's analog FM.

Multicasting
HD Radio technology allows a station to create up to eight separate channels on its assigned frequency. The KTC-HR300 will receive these additional channels, so you'll enjoy the wider selection of entertainment and information provided by participating radio stations. And when you tune to any HD Radio or Radio Data System (RDS) station, you'll see song, title, artist, and other text information on your Kenwood stereo's display.

Tag your favorite tunes
With an iPod® connected to a compatible 2009-up Kenwood receiver, you can "tag" songs that you hear on an HD Radio broadcast for future purchase. The next time you sync your iPod, you can buy the songs you want from the iTunes® Music Store.

Product Highlights:

add HD Radio reception to your compatible Kenwood stereo

Features

HD Radio: HD Radio technology, where available, offers higher quality
sound than conventional analog broadcasts and receives text data. HD Radio
provides FM broadcasts that are equal to CD sound quality and AM broadcasts that
are as good as analog FM stereo broadcasts. HD Radio also provides a variety of
data, including station name, song title, artist name, album name, etc.

Multicasting: In addition to conventional broadcasts, with HD Radio
broadcasting it is possible to choose from up to 8 multicast programs (HD1 to
HD8 and analog). There are also data programs for each program.

Head Unit Compatibility: The
KTC-HR300
tuner can be controlled by most 2003 and up HD Ready Kenwood receivers which
feature either Kenwood's 13-pin connector or Kenwood's KAB 9-pin connector. The
KTC-HR300 is both digital and analog, so the tuner can receive all FM and AM
stations.

Note: Not all HD Radio compatible Kenwood headunits support iTunes
tagging. 2009-up Kenwood DNX, DDX, KDC-MP, and KDC-X models support iTunes
tagging feature. You must have your iPod connected to the compatible Kenwood
receiver for this feature to work.

Receive Mode: You can choose one of the following receive modes:

Auto: analog
broadcasts and digital broadcasts are switched automatically. When both are
being transmitted, the digital broadcast will have priority.

Digital: receives digital broadcasts only

Analog: receives analog broadcasts only

Tuning Mode: The
KTC-HR300 tuner has the
following three tuning modes: Auto seek, Preset station seek, and Manual.

Preset
Memory: You can store
18 FM and 6 AM stations in the receiver's preset memory.

Auto Memory Entry: This feature
selects stations with the strongest signals within the selected band and stores
them in order of their frequency.

Information Display: When
listening to HD Radio, you can cycle through the following information on the
receiver's display: station name, song title/artist name/album name/genre, and
frequency.

iTunes Tagging: The Kenwood KTC-HR300 is also capable of iTunes tagging with compatible
Kenwood receivers. iTunes
tagging gives the ability to tag a song (up to 50) and stores it to a connected
iPod. The next time the iPod is connected to iTunes the tagged songs are
displayed with the option to purchase them from the iTunes Store.

Inputs and Outputs

To Head Unit: 13-pin jack attached to a 57" cable that connects to a
compatible Kenwood head unit which features a 13-pin CD changer port. The
Headunit also comes supplied with a 13-pin to 9-pin KAB adapter to connect to
compatible Kenwood head units which feature the new KAB port.

Note: There are two dip-switches on the tuner that need to be
adjusted based on whether you are connecting the KTC-HR300 to a Kenwood head
unit with a 13-pin port or 9-pin KAB port.

Work quite well

I have the EZ500 head unit and this pairs very well with it. The reception is much better than FM or AM analog, almost as clear as a CD. Some here have said that it runs hot but I have not had that experience, it does get a little warm but not anything worth worrying about.

Bought this unit hoping to use it together with an XM Radio receiver. Normally you're confined to ONE external source and must choose between XM OR HD Radio because of only one 5L connector on the control unit. I tracked down the discontinued EZ-500 receiver originally provided by Hyundai for my '07 Tiburon with the Infinity system - removing the newer Sony head unit that was put in by the first owner. Who goes 'back' to the factory radio? I did, and I'm glad. I wished to bring back the original Kenwood due to the factory amplifier having been pre-tuned to the line outputs of it, and for other reasons. Using a KCA-S220A 2-Changer Switch, I now have the ability to select between and control XM, HD Radio, analog AM/FM and CD from the head unit. The installer of the Sony head unit used a PAC line-level output adapter in between it and the factory amp - which negatively impacted the sound quality. Subwoofer level control, crossover points and other features on the newer Sony head unit were useless with the factory amp. Since I didn't care about either Bluetooth or the iPhone control, I ordered this HD receiver, the legacy radio and the Hyundai dash kit that would accommodate a Kenwood Digital Audio Adapter and Terk XM Radio tuner right underneath the head unit. Combined with a KCA-S220A switch - BOTH HD Radio and XM sources are selectable along with TWO AUX. I wasn't sure how the generation gap between devices would work out but everything plays very well together.

Pros:Great sound quality, works well with my legacy Kenwood EZ-500 radio combined with the KCA-S220A 2-Changer switching device. HD FM quality is a dramatic improvement, well worth the money, as HD Radio was just a curiosity for me until I tried it myself. Both XM and HD Radio sources appear on the head unit so I have HUNDREDS of potential channels, stations and media at my fingertips. Auxiliary on the changer switch is displayed as AUX EXT while the head unit's own is labeled AUX. That, kicks arse.

Cons:Runs a bit warmer than one might expect, but not worrisome. AM reception seems to suffer somewhat, as I had somewhat better AM reception with the Kenwood EZ-500 head unit in analog. With this HD Radio receiver attached, apparently the head unit's built-in tuner is disabled altogether and its antenna connector is apparently no longer used. I'm going to order an antenna 'Y' adapter with signal amp to connect my vehicle antenna to BOTH the head unit and HD Radio tuner and test my results...

Cons:Receiver box is rather large and gets hot. The included cables were not long enough to reach under the passenger seat and the box is too large to fit in the dashboard, so I was forced to mount it on the side of the center console, which isn't ideal.

Hd Tuner added to Kenwood KDC

I had received the Kenwood KDC-BT838U head unit as gift about a year ago. I
had installed it in one vehicle, then I decided to install the head unit in a
different vehicle. I ordered the Kenwood KTC-HR300 HD tuner before I
installed the head unit again. I have had it for a couple of weeks, and the sound
is incredible. The display now shows the songs and artists, plus I get more
radio stations to listen to. I listen to AM radio from time time, and wow - what a
difference for the stations broadcasting in HD on AM. Incredible, well worth the
time, effort and price to convert to HD.

Worked Perfectly With My eXcelon KDC-X790

My older headunit found and used this as soon as I plugged it in. This was a headunit
purchased when nothing but the KTC-9090DAB was available. Glad I waited. The KTC-
HR300 HD was still running cool in use two hours after I installed it. It was harder to dig
out the KDC-X790 manual to make the headunit settings I wanted. The HD sounds great,
and there was no loss from any previous performance of the headunit. The KTC-HR300
just added a lot of digital stations for my pleasure - with their added sound enhancement.
I've had very little drifting between HD and analog, and fast channel acquisition. When
switching back and forth between HD and analog, the change has been seamless. Very
pleased with this unit, in my use.

satisfied customer

product works well ,i am very pleased with this unit,instructions for control are in the head
unit maual,a little diffacult mounting (its cold out the velcro did not want to stick)used some
zip ties.some screw tabs would be better,i put it on the driver side kick panel above the ecu.
in my 06 frontier.there are 2,3 stations with sub channel programs i have found so far,this is
connected to a ddx 512,this unit does not tag i tunes,newer ddx and dnx units do,tho not a
dissapointment.

Works ok... mileage may vary

Overall.. decent unit, works as advertised (picks up digital FM or AM stations
if available).

I do like that if the digital station is lost, and rediscovered shortly after,
the transition isn't too jarring. The tuner kind of blends between
analog/digital and you'll hear the sound change but the music/voice keeps on
going without skipping too much of a beat.

However....
On my 2004 camry xle the AM performance is terrible. I used to be able to pick
up OSU's public station (820 AM) from 80-90 miles away, my range is now 10-15
miles tops.

I realize that my Factory stereo had a diversity antenna (two antenna plugs) but
I didn't know the loss would be so great. I also tend to lose Digital (and swap
to analog) just driving around. I'm hoping to find a way to try the 2nd antenna
in case it's any better (need to find an adapter for the smaller pin) or perhaps
connecting both antenna pins to the HDR.. some forums seem to indicate that can
help.

FM performance is good.. I only listen to one FM station and it works ok...

I'd return it and just use the standard am/fm tuner in the x994 but I'm going to
stick with it in case I find a way to improve things.

Kenwood KTC-HR300

Written By Snakeman, Virginia Beach on Monday, October 18, 2010

I got this to go along with the new Kenwood X994 receiver that I put into my 1999 Grand Caravan. Finding a spot to mount the unit was a bit of a challenge - it ended up in the tilt-out tray under the ashtray/cupholder in the center. I bent the mounting tabs down, and screwed the unit to the sides of the plastic tray, along with the source switcher that I also had to mount (on account of adding Sirius too). The head unit sees and controls the HD receiver with no setup required. I haven't used it much in HD mode yet, but it works flawlessly for normal AM/FM.

Do Your Research on HD Radio

Written By William, Canton, GA on Saturday, June 26, 2010

Before purchasing any HD radio unit you need to do your research on HD radio first. Make sure you'll have coverage in the area where you'll use the unit. I thought I'd have good coverage in the Atlanta suburbs but that's not the case where I live. However, coverage is not the fault of the unit...

When you do have coverage, this unit provides very clear audio and it works very well with the KIV-BT900 which allows selection of Dgital, Analog, or Both. I've had to switch to Analog to get consistent reception near my house, although Digital works great at my office which is nearer to the city.

As you can see from the online info there is no mounting hardware with this unit other than a Velcro strip, so you're pretty much on your own there. I managed to snug mine in behind the center console in my 2000 Mustang GT, but that was more luck than anything else. I would have given a 5-star rating if the unit had any mounting tabs or other mechanical attachment points.
